BS EN 60730-2-4:2007 Automatic electrical controls for household and similar use - Particular requirements for thermal motor protectors for motor-compressors of hermetic and semi-hermetic type
This part of IEC 60730 applies to the partial evaluation of thermal motor protectors as defined
in IEC 60730-1 for sealed (hermetic and semi-hermetic type) motor-compressors.
A thermal motor protector is an integrated control which is dependent on its correct mounting and fixing in or on a
motor and which can only be fully tested in combination with the relevant motor.
Requirements concerning the testing of the combination of motor and thermal motor
protectors are given in IEC 60335-2-34.
This standard applies to thermal motor protectors for motor compressors using NTC or PTC
thermistors, additional requirements for which are contained in Annex J.
This standard applies to the inherent safety, to the operating values, operating times,
and operating sequences, where such are associated with equipment safety, and to the
testing of thermal motor protectors used in or on sealed (hermetic and semi-hermetic type)
motor-compressors.
This standard applies to thermal motor protectors for motor-compressors within the scope
of IEC 60335-2-34.
Throughout this standard the word "equipment" means "appliance and equipment".
Thermal motor protectors for motor compressors not intended for normal household use, but
which nevertheless may be used by the public, such as equipment intended to be used by
laymen in shops, in light industry and on farms, are within the scope of this standard.
This standard does not apply to thermal motor protectors designed exclusively for industrial
applications.
